Since 2002, the validity date for exchange is printed on each
international reply coupon.

The new international reply coupon (Beijing model 2), on sale from 1
July 2006, is valid for exchange until 31 December 2009.

The international reply coupons (Beijing model 1), on sale from 1
January 2002, must be exchanged before 31 December 2006. They will have
no value after this date.

I would like to inform you that International Reply Coupons (IRCs)
issued from 1906 to 1974 (in blue colour) do not have any value for
exchange, but maybe they have an historical value. You may wish to
consult a collector of IRCs to know if the coupon has any financial
value.

You should understand that currently the IRCs issued from 1975 to 2001
(in yellow colour) are exchangeable indefinitely according to the
current UPU rules. However, this kind of IRC cannot be anymore
exchangeable, in term of finances, between the postal administrations
since 30 June 2006. Therefore, it means that some of them do not accept
anymore this coupon for exchange.

The exchange of IRC (after the customer's exchange) between the postal
administrations is managed by a bilateral agreement and if there's no
bilateral agreement, the postal administrations lose money.
